Defending APIs

By: Colin Domoney

Overview of this book

Along with the exponential growth of API adoption comes a rise in security concerns about their implementation and inherent vulnerabilities. For those seeking comprehensive insights into building, deploying, and managing APIs as the first line of cyber defense, this book offers invaluable guidance. Written by a seasoned DevSecOps expert, Defending APIs addresses the imperative task of API security with innovative approaches and techniques designed to combat API-specific safety challenges. The initial chapters are dedicated to API building blocks, hacking APIs by exploiting vulnerabilities, and case studies of recent breaches, while the subsequent sections of the book focus on building the skills necessary for securing APIs in real-world scenarios. Guided by clear step-by-step instructions, you’ll explore offensive techniques for testing vulnerabilities, attacking, and exploiting APIs. Transitioning to defensive techniques, the book equips you with effective methods to guard against common attacks. There are plenty of case studies peppered throughout the book to help you apply the techniques you’re learning in practice, complemented by in-depth insights and a wealth of best practices for building better APIs from the ground up. By the end of this book, you’ll have the expertise to develop secure APIs and test them against various cyber threats targeting APIs.

Shift-Left for API Security

Now that we have a deeper understanding of the methods and techniques used by API attackers, it is time to turn our focus to the core topic of defending APIs against attack.

In this opening chapter of Part 3Defending APIs, the focus will be on how API security can be improved by following a shift-left approach. The best way to avoid vulnerabilities in your APIs is to avoid introducing them in the first place. Although this sounds easier said than done, there is growing evidence from the software-development industry that addressing security concerns as early as possible in the lifecycle results in reduced risk and costs.

APIs are very well suited to a shift-left approach, since the appeal of a design-first approach (using the OpenAPI definition as the source of truth for the API) is fast becoming the de facto technique for API development. This chapter discusses various approaches to incorporating security during the design stage and then...
